Microthreading as a Novel Method for Close Coupling of Custom Hardware Accelerators to SVP Processors

Popis výsledku v původním jazyce

We present a new low-level interfacing scheme for connecting custom accelerators to processors that tolerates latencies that usually occur when accessing hardware accelerators from software. The scheme is based on the Self-adaptive Virtual Processor (SVP) architecture and on the micro-threading concept. Our presentation is based on a sample implementation of the SVP architecture in an extended version of the LEON3 processor called UTLEON3. The SVP concurrency paradigm makes data dependencies explicit inthe dynamic tree of threads. This enables a system to execute threads concurrently in different processor cores. Previous SVP work presumed the cores are homogeneous, for example an array of microthreaded processors sharing a dynamic pool of microthreads. In this work we propose a heterogeneous system of general-purpose processor cores and custom hardware accelerators. The accelerators dynamically pick families of threads from the pool and execute them concurrently.
